Champions That Need Physical Reworks

It kind of hit me recently that there's a lot of champions in the game whose in-game sprites look very outdated and dull compared to models and animations from champions like Zoe, Rakan & Xayah, or Evelynn. And I can sort of understand it, Riot obviously wants to promote and upgrade champs that people somewhat played as, with full reworks like Taric and Eve. I just find it funny how goofy Ezreal, Nunu, and Pantheon look in the game when they stand next to the other, well rendered models. (https://vignette.wikia.nocookie.net/leagueoflegends/images/7/7e/Ezreal_Render.png/revision/latest?cb=20141111175517) Ez be lookin like a homeless man. a grouchy peanut face. Maybe flashing out his color palette, and reanimating his face entirely, would make him more... Attractive. Afterall he is the League's most 'handsome' and beloved boy. (https://vignette.wikia.nocookie.net/leagueoflegends/images/4/41/Pantheon_Render.png/revision/latest?cb=20170922150612) Pantheon has exaggerated limbs. Why are his feet the size of his thigh. His model is so clunky and stiff that the poor guy can't even have a dance animation. :(

(https://vignette.wikia.nocookie.net/leagueoflegends/images/2/2d/Nunu_Render.png/revision/latest?cb=20170921034247) But like, then there's Nunu. A champion that even according to official statistics is the most unpopular, background, picked-by-nobody, champion. And it's pretty sad. He was the first tank in the game, and I think he should get more privilage for that. Instead, he probably has the ugliest in-game model in the entire game. I can see that Riot keeps trying to suggest playing him with each patch and update, whenever I look at the patch notes I see his sad little buffs and then nerfs. Of course, someone is going to say ''Well I main Nunu! He's the only champ I play as! Mastery level 100!''. and that's good for you. He's a fine champion. His ult is kinda meh. The story of a little boy that tamed the Yeti is pretty sweet. He, and all of his skins beside Zombie, just look sad.

-What do you think though? Are there any other game models that look expired? Do you disagree? Let me know~
